I do not subscribe to this mailing list, but feel free to send PM in case you need additional info. You shoudn't :-) After installing Ubuntu 13.10, I noticed kern.log growing faster than you could look at. Within a few working hours, kern.log was >6GB! The reason is that I intentionally disabled WiFi on this laptop by turning the HW switch off. However, this makes iwl3945 write a log entry into kern.log every few microseconds! The workaround is to turn the HW switch on. The bug fix would be to write just a single line to kern.log.
